| Oh - just removed a metal plate from the other side of the set and there is a second inverter there. Looks same as the other. Need to start metering that one now. Colin |

I have one of these sets that developed the same problem a while ago. No backlight but image there. I went in with my meter the other day. The inverter board receives 24 volts from the PSU. F201 is a 5amp SMD fuse near the power connector on the board - this was blown. Replaced it with a miniature wire ended fuse and powered up. The fuse blew again. Checked the Mosfets with the meter and 2 of the 4 are cooked - Q201 and Q204. The output transformer on the board looks good with no scorching. In fact there is no sign of overheating anywhere on the board. OHM SUPPLIES - where is kit62 available from please and do you have any idea of the price. Alternatively does anyone know a source for the inverter board - THERE IS 1 ONLY. The board is marked with the following HPC-1655E and HIU-813-S. There is a paper label that says HRevF-79S7-0939. BTW the mosfets are marked 1H29SP......FDD.....8447L. I've had no joy Googling the mosfets. I don't have an SMD solder station so might be a bit stuck there for the IC. Thanks for any info - I'll monitor the thread. Colin |

|
| Just to let you know, there is a repair kit for these boards, in this case KIT62. It includes the ic, 4 mosfets and the 2 capacitors. The main fault being that the ic can burn up taking out a few if not all of the mosfets. regards Andy |

I have Toshiba 32C3035D too that developed the same problem yesterday - sound OK but no picture. Out of G'tee. I have just done the check with the torch as suggested by minnie and the picture is actually there, so it would appear the panel is not staying lit. What steps should I take to diagnose further to effect a fix. Thanks - Colin |

|
| The problem is due to 2 inverter boards, one of which goes faulty. The cost of the 2 boards as a pair is around £110 from ChasHyde in the UK (CHS). Donberg in Ireland supply the usual offending board (right hand side- also called IPS) separately for about 89 Euros plus VAT. However I obtained both boards on ebay for about £39 for the pair out of a TV with broken screen. Problem is after 3 months we are back to square one- buzzing sound from TV with sound ok and no picture, inverter board damaged again. Toshiba recommend keeping the TV plugged in and in standby always so I reckon it's voltage transients from the PSU killing the inverter boards. CHS also say they only supply the inverter boards as a pair as recommended by Toshiba. Reckon they've upgraded the spec of the inverters too but no one will confirm that. Also wonder if mine blew again because they weren't a pair? Repair expensive and not recommended unless you like a challenge!! |

| Check for bulged caps on the inverter and power supply in both cases. It's a UK model I can't pull a print. | |

| Is the panel staying lit? Take the back off and see if the panel stays illuminated or take a flash light to the front of the panel and see if you see movement. | |
